Kibana has a configuration property elasticsearch.requestHeadersWhitelist.
There are concerns raised on usage of this non-inclusive terminology. Linux team has approved on replacing these non-inclusive terminologies. There are many other tech companies and open-source projects that have removed references to racially-charged jargon from their code for more neutral and inclusive language.
